Exhaust noise

[ohiojack]

A while back I asked a question about a funny noise that sounded like a air leak from a air hose. Well I found it. The cats was plugged. The front cat's screen and honey comb material was all crammed and packed in the rear cat. We shined a flashlight through the exit pipe and could see no light at all!! While driving home, I about lost control of the truck when I kicked it down in passing gear!!!
